amazing Ajax
Script.aculo.us tricks are pretty cool. I especially like the click-and-drag list items (drag from one list to the other- it's in one of the demos). My question is: Is there some kind of onChange() function I can call so I can save the changes in the list order or new additions to one list (items dragged in from the second list)? It's not a problem for me to populate a list from a database, but I would like to save some kind of array of the items from a list where items have been added, removed, or rearranged.

The general answer is you want to respond to something like an onchange event and send an http request back to the server, where a server side script can make updates to the database. That Ajax.Updater does something along those lines.
